Display goes black when diagnostic test is launched

Every time I run a diagnostic test the screen goes black either in the initial quick test or in slow or extended test. I have to force restart it to get it working again.

I know this macbook had previous water damage but it was working fairly fine.

When I connect an external display (HDMI) the laptop restarts within few minutes and keeps restarting until I disconnect the display.

I tried SMC and NVRAM reset, same issue.
